Fujitsu Laboratories of Europe has today unveiled a new technology for smart design and manufacturing at the Fujitsu Innovation Gathering 2016, involving a new method for computing the similarity of 3D models. The new 3D model search solution forms part of Fujitsu’s research and development into machine learning-based solutions for smart design applications, and achieves over 96 percent accuracy for automatically locating elements in large component databases. The solution uses the power of deep learning to accelerate the process of mechanical design, enabling mechanical designers rapidly and efficiently to locate existing models, their components and associated manufacturing data – a process that currently accounts for more than 50 percent of the design process.

Developed to improve design productivity and quality, Fujitsu’s technology can benefit organizations in multiple ways. One example is in product data management, where large 3D model repositories can be rapidly labeled and augmented with meta-data. Model clustering tools based on Fujitsu’s 3D model search technology can reduce the time of labeling large collections of 3D models from days and even weeks to a few hours. The 3D model search solution can also significantly speed up the design process when integrated into a designer’s development environment. For example, it enables reviewers directly to locate elements of interest such as clips, bosses, ribs etc rather than having to search manually, enabling much faster design reviews. It can also assist with the rapid identification of design issues related to particular shapes before a prototype is made.

This new technology forms one component of Fujitsu’s machine learning-based solutions for smart design, combining its extensive existing library of proprietary mechanical design data with a variety of other technologies under development. Fujitsu Laboratories of Europe’s Chief Executive Officer, Dr Tsuneo Nakata, expands on the solution’s future potential : “The ultimate research and development objective is to create a design system in the future that automatically adds missing semantic information to 3D models, with complex product design rule checks capable of being defined and enforced. However, the applications of our new 3D model search technology are by no means limited to the field of manufacturing. It is an exciting development that has considerable potential – for example in healthcare and medicine, or any application where there is a need to compare 3D models extremely accurately, identify what they represent and ascertain whether they are normal or anomalous.“

The Technology Behind the 3D Model Search Solution At the heart of Fujitsu’s technology is a deep neural network that is trained on a combination of 2D image data, more than 1 million images from the ImageNet database , and 3D model data from Fujitsu’s own manufacturing designs – the latter being key to achieving high accuracy on 3D Computer Aided Design (CAD) models. The deep network is used to extract feature vectors from 3D models which, together with model dimensions, form a powerful shape descriptor that is independent of the orientation of the 3D model.

Taking only a few seconds, the search process generates a descriptor for the search item, which is then compared against tens of thousands of models in the database. The search then outputs an ordered list of similar models (see Figure 1). Current accuracy of this new method is over 96 percent for several classes of CAD models, with ongoing work to add more classes.
